如何使用按钮的onpressed属性在flutter中使用Stateful中的remove()和setState()从列表中删除一个值？

class MyStatefulWidget extends StatefulWidget {
  @override
  _MyStatefulWidgetState createState() => _MyStatefulWidgetState();
}

class _MyStatefulWidgetState extends State<MyStatefulWidget> {
  List<int> listValues = [1, 2, 3, 4, 5];
  
  // ...
}

class _MyStatefulWidgetState extends State<MyStatefulWidget> {
  // ...
  
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('My App'),
      ),
      body: ListView.builder(
        itemCount: listValues.length,
        itemBuilder: (context, index) {
          return ListTile(
            title: Text(listValues[index].toString()),
            trailing: IconButton(
              icon: Icon(Icons.delete),
              onPressed: () {
                // 调用setState方法以更新UI并删除指定的值
                setState(() {
                  listValues.removeAt(index);
                });
              },
            ),
          );
        },
      ),
    );
  }
}
